Call me back when hair starts growing on his palms

My father is a physician,
so I often get to hear amusing stories from his days as a resident in
the ER. He told me one yesterday that I thought was good enough
to share. (In order to understand this story you need to know that
the cardiacintensive care unit of most hospitals has a
security camera on each bed, so the person at the nurses station can
watch all of the patients all the time. There is also a cool panel
of ekg and blood oxidation monitors that goes with each bed.)

A friend of his, a cardiologist, had been working for about eighteen
hours straight and was covering the ER and cardiac intensive care unit.
Finally at about three thirty in the morning he got a chance to rest.
He went to the on-call lounge and fell asleep quickly. But soon after,
the phone rang and it was one of the nurses on call in the cardiac
intensive care unit.
